=== Spring Config Server Store

The Spring Config Server Store extends the Vert.x Configuration Retriever and provides the
a way to retrieve configuration from a Spring Server.

==== Using the Spring Config Server Store

To use the Spring Config Server Store, add the following dependency to the
_dependencies_ section of your build descriptor:

* Maven (in your `pom.xml`):

[source,xml,subs="+attributes"]
----
<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-config-spring-config-server</artifactId>
  <version>3.4.1</version>
</dependency>
<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-config</artifactId>
  <version>3.4.1</version>
</dependency>
----

* Gradle (in your `build.gradle` file):

[source,groovy,subs="+attributes"]
----
compile 'io.vertx:vertx-config:3.4.1'
compile 'io.vertx:vertx-config-spring-config-server:3.4.1'
----

==== Configuring the store

Once added to your classpath or dependencies, you need to configure the
`link:../../jsdoc/module-vertx-config-js_config_retriever-ConfigRetriever.html[ConfigRetriever]` to use this store:

[source, js]
----
var ConfigRetriever = require("vertx-config-js/config_retriever");
var store = {
  "type" : "spring-config-server",
  "config" : {
    "url" : "http://localhost:8888/foo/development"
  }
};

var retriever = ConfigRetriever.create(vertx, {
  "stores" : [
    store
  ]
});

----


Configurable attributes are:

* `url` - the `url` to retrieve the configuration (mandatory)
* `timeout` - the timeout (in milliseconds) to retrieve the configuration, 3000 by default
* `user` - the `user` (no authentication by default)
* `password` - the `password`
* `httpClientConfiguration` - the configuration of the underlying HTTP client
